If Jimmy does survive, experts suggest it would be highly unlikely that he would make it to the racetrack.

The horse, by champion stallion Redoute's Choice out of mare Helsinge, was bought amid much fanfare at April's Easter yearling sales, just a few days before his famous relation was to race for the final time.

His price of $5 million set a new record for a yearling bought in Australia.

Jimmy is also related to now-retired champion three-year-old All Too Hard, and has a half-sister named Belle Couture who is expected to make her racetrack debut in the coming months.

The team from BC3 Thoroughbreds bought Belle Couture in 2012 for $2.6 million.
